You might have gotten output, and most of it might look just fine, but what about the error that wasn't caught? Maybe it renders something incorrectly, but if it's buried in page 42 of a page document, when will you notice? Maybe the error rendered correctly in the web version of your document, but incorrectly for the print version. DocBook, like all XML, is famously strict. Experiencing errors is never easy.
It's not fun to watch your work fizzle out in a pool of illegal tags and syntax errors instead of building into a beautifully rendered EPUB, webpage, or PDF. To get around that disappointment, most processors accept an option to temporarily ignore errors, such as --skip-validation , but ultimately failure is important. Failure identifies imperfections in your source and protects you from unpleasant surprises in your product. DocBook sometimes has a reputation for being hard to learn.
I have found that more often it's not DocBook, but the unique tool chains people build around it, that have the steep learning curve. Do you want to write an article or a book? Compared to Markdown and AsciiDoc , DocBook appears complex, but if you consider all the rules that aren't intuitive in structured text, DocBook's rules don't seem so bad. Learning syntax from the original Markdown spec was often a process of trial and error, followed by a series of desperate internet searches, which meant wading through all the different Markdown flavors and parsers for the best applicable candidate for a correct answer.
CommonMark , a project dedicated to defining a more arduous and strict specification, has helped, but users are often lulled into a false sense of security by how easy it is to learn the basics, only to find that achieving advanced results introduces a surprise learning curve.
Luckily, Markdown accepts HTML as a fallback markup option, and there are several tools and Markdown variants out there to make up for what the original spec lacks. Even so, if you're writing complex documents for several different output targets, it may not be as easy as it looks in all the "learn Markdown in just 15 minute"-style blogs.
That's all there is to it. It's about the same as learning HTML: learn the basics in the first few minutes, and keep a reference handy to learn more as needed. Depending on how much you know about XML, there can be a few surprises, but the DocBook website clearly defines valid parent and child relationships for each and every tag, and each entry for each tag provides big blocks of examples. Finally, DocBook is important because it provides data about your data.
DocBook tags aren't meant to dictate a style over your content, but to classify the information you are trying to convey. DocBook tags provide semantic meaning to your words. Semantics might not seem that important to you now, but here are two great examples of times that metadata became truly important in the real world:.
Here's a quick and easy way to get started with DocBook. This method emphasizes learning DocBook tags and syntax rather than building a complex and flexible tool chain. If you are ever in doubt about whether or not a tag is required, just refer to the tag's documentation. The synopsis section tells you what is required and what is optional. And that's all there is to it.
The more you write in DocBook, the more tags and attributes you learn, and eventually you'll probably find it hard to go back to a less explicit format. The default DocBook render from most processors aside from Pandoc looks a little something like this:.
It's professional, but painfully so. Still, it's an important foundation upon which additional styles can be applied. Otherwise, here's a brief introduction to XSL and the xsltproc command. If you install DocBook from your Linux distribution or from the DocBook website, you are installing all the default DocBook stylesheets. These serve as the fallback styles whenever you use a tool like xsltproc or xmlto.
Load the DocBookTemplate. Display the Style list by pressing F Now choose 'All Styles', so that all available styles are displayed. If you wish to see how sections are nested, use the F5 key to Display the Navigator window.
Expand the sections tag, to display the layout of the sections within the document. You can skip to the start of a given section, by double-clicking on it. Skip to the ArticleInfo Section by double clicking on it in the Navigator window. Select the 'Document Title' style from the stylelist and then type the Document Title.

Additionally, the Misc Files category contains of other files. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. How to solve such a problem? If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened. If it is not, installation may solve the problem, as most applications create file associations during installation.
We suggest using the websites of software developers. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file.
